Specification of Letters Patent.

Patented April 21, 1908.

' Application filed January 28, 1907. Serial No. 354,596.

To all whom it may concern:

Be'it known that I, DAVID STEWART, a citizen of the United States, andresident of Chehalis, in the county of Lewis and State of Washin ton, have invented certain new and useful mprovements in Burglary-Preventing A paratus, of which the following is a speci cation.

- cated' valuables,

This invention relates to burglary pre-' venting a paratus.

It has or an object to provide an apparatus which will deliver fumes into a room, vault, car or'other chamber thus preventing the entrance of a burglar even after hehas secured access to the chamberin which the valuables are contained.

. Other and further objects will appear in l e more; I

the following descri tion and wil particularly pointe out in the appended claims:

In the drawings-Figural is a ortionof a building showing a portion ofla c amber for ,contaimng valuables, and a portion of a ch amher which leads tosaid first mentioned chamher; and Fig. 2 isa detail pers eetive view ofthe valve 'dlSk and its contro sprin being-under tension.-

Re erring more particularly to'the drawing lever, the

ings, 1 indicates a tank or receptacle linedwith orcelain, "lass or other non-corrosive material .and'fiafapted' to contain, a-fuming flui either a as or a liquid 'such, for 111- stan'ce, as'spirits of ammonia, chloroform,

ether, formaldehyde acid or gas, carbonic acid 'as,etc., either'singly' acid gas, sulfuric or in coinblnation; .T s tank can be suitthe shocks from explosions breaking the same, although even should the tank be destroyed .by explosion,

it would still be effective in distributing the fumes. This tank preferably arranged within the room, vault, car or other chamber containing the valuables and has a valve 2 connected therewith and controlling a discharge 3 in'the form of adepcnding'plpc closed at its lower end having lateral (l1S-'- char e op'enings'4 or connected witlrrperforatec ipes or nozzles to' spray the, fluid when t e valve isopenedt Secured to the valve stem, which extends through the wall 15 to the outside of the chamber, is a disk 5 which has aperipheral portion 6 to which is secured one endof a tape 7, the other end of the tape being secured to one end of a splral spring 8 whichis in which is 10-- ventin to foil burglars when the use of exp chamber, and an expl charge from said chamber, m

anchored in any suitable manner as at 9. When the valve 2 is closed, the tape is wound about the disk 5 and the spring is under ten=- si'on, thus tending to 0 en the valve.

, To maintain the va ve closed until an explosion takes place or it is desired to release the valve,'a lever 10'pivoted at 11 intermediate of its ends, has one end formed to engage teeth 12 on av flange 13 of the disk 5. The reater portion of the flange 13 is SIIIOOlfil and therefore presents no obstruction forthe lever to engage so that once the disk is released, there is no-dan er of the lever reengaging the teeth of the disk and thus rethe complete opening of the va ve. The ot er and of the lever isiwidenedso that it may better receive vibrations produced by an explosion. 3

of the lever, the vibrations produced by an explosion, there is arranged a funnel shaped member 14, the smaller end of which'is directed toward the widened'end of the lever. This lever may also -be' operatedmanuallyand for this purpose aoon trolling'cable 16 is connected to the widened end and .leadsto any suitable point, as, for instance, when the apparatus is employed in a bank, to the cashiers-desk, thus adapting the apparatus osives is unnecessaryqtO gainaccess toa chamber.-

Of course, all parts of the apparatus on the outside of the chamber for containing valuables should-be suitably incased to prevent an explosive.

- Having thus described invention, what I claim and desire to secure by Letters Patent'is: .1. .The combination ofa fumin fluid containing chamber, an automaticalFy operated valve controlling the discharge from the controlling the valve.

' 2. The combination of a'fumin fluid containing chamber, a valve controlling the disans tending to open the valve, and means'f r releasing the valve to permit it to open automatically.

3. The combination of afuining fluid con-- taining chamber, a valve controlhn'g the discharge from the chamber, a'spring acting to open the valve, and means for re easing the valve to permit it to open under the action of the spring.

- 4. The combination of a fuming fluid con- To concentrate on the shock receiv ng end a burglar tampering with'them before using 'osio'n operated means ees,eoo
